ABSTRACT:
An agricultural implement of the type capable of folding from a wide operating mode to a narrow transport mode. The folding involves forward folding of the right and left wing sections alongside the central, fore-and-aft hitch. Featured are support wheels respectively for the wing sections which are selectively movable from the extended, forward positions in the operating mode to retracted or rearward positions in the transport mode to enable the wing sections to be more closely folded relative to the hitch and thus to achieve a narrower transport width. The closely spaced end-to-end relationship of the wing sections in operating mode provide for relatively narrow row spacing because only the hitch intervenes between the proximate ends of the sections.
